Event ID - 4012

Event Id4012
DescriptionThe following GroupWise users have not granted sufficient access rights to the migration account: <user name>
Event InformationAccording to Microsoft:
When the Migration Wizard migrates a mailbox, it always attempts to verify that proxy rights have been granted to the migration account, even if the migration account is the same as the user account that is associated with the mailbox.
To prevent this problem from occurring, always grant GroupWise proxy rights to the migration account for all the mailboxes that you are attempting to migrate, even if the migration account is the same as the user account associated with one or more of the mailboxes.

Before migrating Novell GroupWise mailboxes to Exchange, each GroupWise user must grant proxy access to the Novell GroupWise account used to perform migration. Users must grant proxy access to their mailboxes. For more information, see the Exchange online documentation.
